Tabbing from a toolbar component to a JInternalFrame either is giving focus to
wrong frame or failing to bring the correct frame to the front. This is very
bad as keyboard navigation is a high priority test criteria for our testors and
analysts. There is no keyboard navigation to fix this and no focus event to
trap on JInternalFrame or JDesktopPane. The focus event can be trapped by
subclassing and overriding the isFocusTraversable(), but this has the
undesirable effect of creating a tab-stop with no visible clue to the user. To
make it work right the focus listner must perform either transferFocus() or
moveToFront(). Either way, the JInternalFrame does not receive an 'Activated'
event. Note: this is a bug resubmitted at your request with sample code.

public class TestFrame extends JFrame {
